Application filed May 22,1903. Serial No. 158,310.

T 0 It whom it may concern:

Be it known that I, WILLIAM CAMERON, a citizen of the United States, and a resident of Chicago, in the county of Cook, in the State of Illinois, have invented new and useful Improvements in Machines for Making Can- Bodies ,of which the following is a specification.

This invention relates to a machine for making sheet-metal can-bodies or tubes of that kind in which the meeting longitudinal edges of the sheet forming the body or tube are joined by interlocked seam-hooks formed on the edges of the sheet. The machine is of that ty e in which the sheet-metal blanks from w ich the can-bodies are formed are conveyed to an edging mechanism in which the opposite longitudinal edges of the blank are bent to form oppositely-projecting seamhooks and are then conve ed to a forming mechanism in which the b anks are bent by forming-jaws into tubular form around an expanding forming-horn with the seam-hooks o 'verlapped, the seam-hooks being interlocked by ex anding the horn and the interlocked seam-looks pressed or hammered to tightly close and complete the seams, after which the bodies are removed from the forming horn ready to have the seams soldered.

The object of the invention is to provide a rapid, efficient, and desirable machine of this character which is of simple, strong, and inexpensive construction.

In the accompanying drawings, consisting of four sheets, Figure 1 is a plan view of a canbody-making machine embodying the invention. Fig. 2 is a central vertical sectional elevation thereof. Fig. 3 is a fragmentary horizontal section, on an enlarged scale, through the expanding-horn and associated parts. Fig. 4 is a front sectional elevation of the machine. F 5 is a fragmentary sectional elevation snowing the body-forming mechanism. Fig. 6 is a transverse sectional elevation in line 6 6, 2. Fig. 7 is a transverse sectional elevation of the edging mechanism.

Like letters of reference refer to like parts in the several figures.

The main frame of the machine, which may be of any suitable construction, comprises in the form shown in the drawings a main upright standard or casting A, an upri ht transverse standard a, arran ed in rear of the casting A, and a horizonta bed-plate a, which connects and is supported by said standards. The body-blanks are fed successively to a horizontal support on the bed in position to be carriedforward to the edging mechanism by a primary conveyer. The blank-support consists of parallel horizontal side and center rails B b, secured to supporting-blocks on the right flanges 1), between which the blanks are placed and guided and which are adjustably secured by bolts 1) or in any other manner permitting the side rails to be adjusted nearer to or farther from each other to accommodate blanks of different widths.

The primary conveyer for carrying the body-blanks to the edging mechanism is constructed as follows: C represents horizontal reciprocating feed-bars arranged parallel with and between the center and side rails of the blank-support. The bars are provided with feed-dogs c, which are pivoted to swing vertically in openings in the feed-bars, the rear ends of the dogs being weighted, so as to hold the front ends thereof up above the tops of the feed-bars in position to engage the rear edges of the body-blanks to move the same forwardly on the blank-supports in the forward movements of the feed-bars. When the bars move rearwardly, the front ends of the dogs are depressed by engagement with the blanks and pass beneath the blanks. The feed-bars are secured to horizontally-reciprocating slides c, which are provided with depending reduced portions or ribs which engage and work in longitudinal slots 0 in the bed-plate. (See Fig. 6.) The slide-bars c are connected beneath the machine-bed by a head or yoke 0 The feed-bars are rec ,lrocated by the following mechanism: D, Figs. 2 and 4, represents a horizontal dri ve-shaft which is journaled in suitable bearings on the front side of the main standard and is provided at one end with the usual ti ht and loose drive-pulleys d d. The drive-s aft is provided. at its inner end with a gear-wheel d", .which meshes with and drives a gear-wheel e, loose on a horizontal shaft E, hereinafter termed the hammershaft, which is journaled in suitable bearings on the front side of the main standar dabove the drive-shaft. The loose gearwheel e is operatively connected with the hamrnensh aft to drive the la tter by a clutch i P" of any suitabi construction, which is opbed. The side rails B are provided with uperated by a lever e which extends to a point within the reach of the operator. In the construction shown the clutch consists of a collar splined on the hammer-shaft and provided with teeth adapted to interlock with teeth on the gear-wheel e when the clutchcollar is moved toward said gear-wheel. A gear-wheel e fixed to the hammer-shaft, extends through a hole in the main standard and meshes with and drives a gear-wheel a, mounted .on a shaft 6, which is supported in suitable bearings on the rear side of the main standard. The gear-wheel e meshes with and drives a gear-wheel secured to a horizontal crank-shaft F, w 'ch is journaled in suitable bearings f on the rear side of the main standard. The crank-shaft F is provided with a crank-disk f the wrist-pin of which is connected by a pitman or link f with the head connecting the feed bar slides.

G represents swinging dogs which are pivoted at their upper ends to the upright flanges of the side rails of the blank-support, with their lower free ends adapted to engage the body-blanks to hold the latter from rearward movement during the rearward move ment of the feed-bars.

9 represents bent clamp-springs, which are secured at their upper ends to a cross-bar g, which is seated in notches in the vertical flanges of the side rails of the blank-support and retained therein by horizontally-swinging arms g pivoted on the side rai s. The free forwardly-extending ends of the clampsprings bear on the tops of the blanks at their opposite sides and press them firmly down on the supporting; rails. These clampsprin s arrest the lanks before they enter the e ging mechanism and prevent the blanks from being thrown partially into the edging mechanism by the primary conveyer when the machine is operated rapidly.

The can-body blanks can be placed successively upon the blank-support in position to be engaged and carried forward by the pri mary conveyer; but as it requires g'reat exertion and rapidity on the part of the person feeding the machine to supply the blanks fast enough for the machine when in rapid operation a feed mechanism is shown for supp ying the blanks to the primary conveyer. The attendant supplies sheets long enough to produce several body-blanks to the feeding mechanism, which is provied with a cutter or shears by which the long sheets are cut into blanks of the proper size for the bodies, these blanks being fed to the primary conveyer by the feed mechanism. The latter is constructed as follows: Two pair of feedrolls H H are journaled in a suitable upright frame h on the bed of the machine. The upper roll of each pair bears in boxes which are movable vertically in guides or ways h in the sides of the frame h and is pressed toward the lower roll, so as to grip the sheet between the rolls by springs if. The tension of the springs is adjusted to exert the desired pressure on the rolls by adjusting-screws 71/ The rolls are driven by any suitable mechanism. For instance, a horizontal shaft I is j ournaled beneath the machine-bed and is provided with a sprocket-wheel L, around which and a sprocket-wheel i on the journal at one end of each of the lower rolls runs a sprocketchain '8 The upper rolls are driven from the lower rolls by interineshing gear-pinions on the journals for the upper and lower rolls, respectively. The shaft I is driven from the crank-shaft F by a longitudinal shaft provided with bevel-gears j j", meshing with bevel-gears on the crank-shaft and shaft 1.

7' represents a vertical cutting-plate which is arranged between the two pairs of feedrollers. The cutting-plate is provided with a horizontal opening on the plane of the spaces between the rollers of each pair through which the sheet passes.

7' is a knife or cutter which is mounted to reciprocate vertically in ways on the rear standard. The knife is moved across the opening in the cutting-plate and cuts the sheet by a shearing action in a well-known manner. The knife is reciprocated by a cam j, secured to the shaft 1 and provided with a cam-groove, into which projects a stud or roller secured to an arm projecting from the knife.

1' represents a stationary vertical plate arranged in front of the front pair of rollers and provided with a guide-opening through which the blanks pass, and j is a is mounted to reciprocate vertically in suitable guides on the frame of the feed mechanism. The lower end of the gage-plate is connected to one end of a lever g, which is pivoted intermediate of its ends to the bed of the machine and is connected at its opposite end to the reciprocating knife, thus causing the gage-plate to move oppositely to the direc' tion of movement of the knife. The front edge of the long sheet is placed by the operator between the rolls of the rear pair, which grip the sheet and move it forwardly while the knife is down until the front edge of the sheet contacts with the gage-plate and is thereby arrested, the rollers slipping to perniit the stoppage of the sheet. The knife thus rises and severs a blank from the sheet and the gage lowers out of the path of the blank, which is moved forwardly by the front pair of feedrolls and dropped on the blanksupport in position to be engaged and moved forwardly by the rear pair of feed-dogs on the primary conveyer. The knife then lowers, the gage-plate rises, and the rear pair of feedrolls feed the remainder of the sheet forwardly against the gage-plate. A blank is thus cut and dropped on the blank-support prior to each forward movement of the primary conveyer.

IOO gage-plate which The edging mechanism which forms the seam hooks on the opposite longitudinal edges of the body-blank is constructed as follows, (see particularly Figs. 6 and 7:) K K re resent edger frames or boxes, in which the e ging mechanism is mounted. These frame are supported on the bed and provided with adjusting-screws k for operating the frames nearer to or farther from each other to properly operate upon blanks of different widths. The frames are secured when adjusted by clamping-bolts or the like Zc. The edgerframes are provided at their inner ends with horizontal supports k k for the side edges of the blank. These supports are arranged in front of the side rails of the blank-support, with their top faces on the horizontal plane of the supporting-faces of the side rails of the blank support. The blank is moved onto the supports of the edger-frames, where it is temporarily held by a weight Zc, Fig. 2, arranged between the two edger-frames. The weight k rests upon the center rail of the blanksup port and is provided at its rear end with ver tical pins Z0 which engage loosely in holes in the cross-bar g. The rear end of the weight is beveled, so that the blank can pass under the weight which holds the blank in proper osition in the edging mechanism until it is firmly clamped by the clamping-levers of the edging mechanism. L L represent the clamping-levers, which are pivoted, respectively, to the edger-frames K K and are provided with depending clamping portions located above the supports k k of the edgerframes and between which and said supports the blanks are firmly held by the clampinglevers while the hooks are being formed.

The clamping-levers are operated to clamp and release the blanks by the following mechanism: Z represents a horizontal shaft journaled in suitable bearings on the rear side of the main standard above the edging mechanism. This shaft, which is hereinafter termed the edger-shaft, is driven from the crankshaft F by a vertical shaft Z, journaled in suitable bearings on the main standard and provided at its opposite ends with bevel gearwheels Z l, which intermesh with bevel gearwheels Z Z secured, respectively, to the crankshaft F and the edger-shaft Z. The edger-shaft is provided with a cam Z, having a earn-groove into which projects a stud or roller secured to an arm projecting from a slide Z, which is mounted to reciprocate vertically in suitable ways Z on the main standard. The slide Z is connected to the inner ends of the clamping-levers by links Z, which are preferably adj ustable in length. M M represent the hookforming tools which are secured to verticallyswinging levers m, pivoted at their outer ends on slides m, arranged to slide horizontally toward and from each other in ways m on the lower portions of the edger-frames. WVhen the blank is fed into the edging mechanism,

the hook-forming tool M stands above and the tool M below the adjacent edges of the blank. The hook-forming levers are provided with adjustable gage-pieces m m, re spectively, which in the normal position of the levers engage and properly center the blank 011 the supports of the edger-frames. The hook-forming levers are connected by adjustable links m to slides m, arranged to reciprocate vertically in ways m on the main standard. The slides are provided with projecting arms which carry studs or rollers which project into cam-grooves formed in cams m m, secured to the edgershaft. These cam-grooves are so shaped that the -hookforming tools are moved simultaneously in opposite directions, one up and the other down.

a n represent bell-crank levers which are pivoted at their angles on the edger-frames. The bell-crank levers have depending arms, which engage in slots in the slides carrying the hook-forming tools, and horizontallyprojecting arms, which are connected by adj ustable links to slides a, mounted to reciprocate vertically in ways it on the main standard. The slides n are provided with projecting arms, which carry studs or rollers,

which project into cam-grooves formed in cams n a, secured to the edger-shaft. The cam-grooves of the cams n n are so shaped that the slides are moved simultaneously toward and from each other. The body-blank is fed into the edging mechanism by the primary conveyor and is left on the supports of the edger-fran'ie with one edge overhanging a beveled lip n on the support of the edgerframe K and the other edge projectin beyond a beveled lip n" on the clamping-Tever L. The clamping-levers are then lowered by their described operating means and firmly grip and hold the blank. The cams for the hook-forming tools then operate to move the tool M downwardly and the tool M upwardly, so as to bend the edges of the blank, one down and the other up, as shown in Fig. 7. The slides carrying the hookforming tools are then moved toward each other by their cams, so that the hook-forming tools bend the partially-formed hooks inwardly over the beveled lips on the support of the edger-frame K and the clamping-lever L to complete the hooks. The slides are then separated, the hook-forming levers returned to their initial position, and the clamping-levers raised to release the canbody blank, which is then moved forwardly by the primary conveyer to the body-forming mechanism.

The body-forming mechanism comprises a stationary expanding forming-horn, swinging jaws which shape or bend the blank around the horn to conform to the shape of the latter with the seam-hooks overlapped, means for expanding the horn to interlock ICC the seamhooks, and a hammer for pressing the hooks to complete or close the seam.

The forming-horn projects forwardly from the main standard beneath the path'of the blank as it is fed forwardly from the edging mechanism through a suitable opening in the main standard. The horn comprises a stationary section 0, which is provided at its rear end with a shank passing through a hole in the main standard and secured to the latter and to the bed-plate, and a swinging expandingwing O which is hinged at its upper edge to the stationary section and adapted to swing away therefrom to expand the canbody for the purpose of interlocking the seam-hooks. The lower side of the stationary section of the horn is provided with a longitudinal groove which receives the seam when the latter is pressed by the hammer. The expanding-Wing is moved outwardly by an expanding-pin P, which is movable longitudinally in an axial hole in the stationary section of the horn and is provided with inclined faces p, adapted to engage pins 29 projecting inwardly from the expanding-wing. The expanding-pin is moved longitudinally by mechanism hereinafter described.

Q, Figs. 4 and 5, represent supports which hold and guide the side edges of the hooked blank when it is moved forwardly to the body-forming mechanism. These supports are arranged at opposite sides of the horn to swing on shafts g, secured at one end to the main standard and at the other end to a frame g, supported by horizontal bars q, secured at their rear ends to the main standard and at their front ends to means not shown. The supports Q are provided at their inner edges with lips or flanges which are normally held substantially on the horizontal plane of the top faces of supports on the edger-frames by counterbalancingweights g secured to the supports Q. When the bod -blankis moved into the body-forming mechanism, it rests upon the forminghorn and swinging side supports in a substantially horizontal plane, as indicated in Fig. 4. R represents a clamping-block which is arranged above the horn and is movable vertically in a guide-opening in a bracket 1, projecting forwardly from the main standard. The rear lower corner of the clampingblock is beveled, and when the blank is moved into the body-forming mechanism it lifts the clamping-block, the weight of which prevents the blank from being thrown beyond the forming-horn by the primary conveyer. The clamping-block is positively forced downwardly to clamp the blank between the same and the horn by a rock-shaft or roller 1", which is journaled in suitable bearings on the main standard above the clamping-block and is provided with inclined faces 1, adapted to engage inclined faces on an upwardly-projecting portion 1 of the clamping-block. The rock-shaft is provided at one end with a rock-arm 1", connected by a link 1' with one arm of a lever 1", which is pivoted on the main standard with its other arm extending through a hole in the standard and provided with a stud or roller which engages in a cam-groove in a cam 1", secured to the edger-shaft. The lever is rocked by this cam and oscillates the rock-shaft r to clamp the blank at the proper time.

S represents the swinging jaws for bending the blank into body form around the horn. These jaws are pivoted to a shaft 8, which is secured at its rear end to the main standard and at its forward end to the yoke or frame q. The forming-jaws are connected by links to the inner ends of levers s, which are pivoted on ins s projecting from the main standard, an are connected at their outer ends by adjustable links .9 to slides s, mounted to reciprocate vertically in suitable ways 3 on the front side of the main standard. The slides are provided with projecting arms which carry studs or rollers projecting into camgrooves formed in cams s, secured to the hammer-shaft E. These earns 8 through the medium of the slides, levers, and connecting-links, swing the forming-j aws downwardly toward each other, so as to embrace the horn and bend the blank around the same. The link connecting one of the levers with its operating slide is so adjusted that said jaw moves somewhat in advance of the other for the purpose of insuring the proper overlapping of the seam-hooks. When the formingjaws engage the blank and force the sides of the same downwardly, the swinging side supports for the blank tilt, as indicated in Fig. 5, until the edges of the blank disengage the sup ortinglips or flanges on the side supports.

T e horn-expanding pin is reciprocated to expand the horn and cause the overlapped seam-hooks of the blank to interlock by the following mechanism: T represents a slide which is movable horizontally in ways t, formed by the bed-plate and horizontal ribs t on the slides c of the primary conveyer. The rear end of the expanding-pin P is secured to the slide T in any suitable manner. The latter is provided with a depending lug which passes through a slot in the bed-plate and is connected to one arm of a bell-crank lever t which is pivoted at t on a bracket t projecting rearwardly from the main standard. The other arm of the bell-crank lever is connected to a fixed arm on a slide U, which is mounted to reciprocate vertically in suitable ways a on the main standard. This slide. which constitutes the movable support for the hammer which closes the body-seam, is reciprocated by a pitman u, connected to the slide-head and to a crank on the hammershaft E. When the hammer-slide is raised to press the seam and before it strikes the seam, the expanding-pin is moved rearwardly by the described connections, and its inclined faces engage the pins on the expandin wing of the forming-horn, thereby moving t e latter outwardly so as to expand the can-body and cause the seam-hooks to interlock.

While the horn and can-body are main tained in their expanded condition, the hammer V on the hammer-slide strikes the interlocked hooks, ressing or closing the seam and forcing t e latter inwardly into the groove in the bottom of the forming-horn in the usual manner. The hammer is preferably adjustable on the hammer-slide by means of ordinary adjusting-wedges 22. While the hammer V is shown as a separate block on the supporting-slide U, it moves with and is, in efiect, a part of the slide, and it need not be a separate part.

W, Figs. 3 and 6, represents stripping fingers or devices for moving the can-body off of the formin horn. These fingers are pivoted interme iate of their ends on vertical pivot-pins w, secured to the slide carrying the expanding-pin, on opposite sides of the latter. The rear ends of the stripping-fingers are connected by a spring or springs w to the rear end of the horn-expanding pin or other suitable part movable with the slide T. The springs tend to draw the rear ends of the stripping-fingers to ether and spread or separate the front ends thereof. The inward movement of the rear ends of the strippingfin ers and outward movement of their front en s is limited by adjustable stop-screws w on the slide T. The forward portions of the stripping-fingers work in longitudinal grooves in opposite sides of the forming-horn and are surrounded by the can-body when the latter is formed on the horn. When the horn-expanding pin is moved rearwardly and the seam has been pressed by the hammer, the front ends of the stri ping-fingers are drawn rearwardly out of t e can body and are spread by the springs w, so that when the stripping-fingers move forwardly upon the downward movement of the hammer-slide the front ends of the fingers engage the rear end of the can-body and push the latter off of the forming-horn. The expanding-pin and stripping-fingers are carried by the same slide and move together, the expanding-pin acting to expand the forming-horn on the rearward movement of the slide and the stri ping-fingers acting to push the body off of t e forming-horn upon the forward movement of the slide.

When the body is shoved off of the forming-horn,it passes onto the horn or body support of the soldering mechanism, the front end of which horn is shown at x. The body is then in position to be engaged by the con veyer-dogs w of the conveyer for the soldering mechanism and moved forwardly ast the soldering devices. The soldering mec 1an ism and its conveyer are not fully shown in this application, but arefully shown and described in my a plication for United States Letters Patent fi ed on the 16th day of April, Serial N 0. 152,867 "It is only necessary for an understanding of the present machine to state that the conveyer of the soldering mechanism is operated from a shaft 00 which is driven by a ear-wheel a on said shaft meshing with theToose gear-wheel e, secured to the hammer-shaft. This wheel is driven positively from the drive-shaft D and the conveyer of the soldering mechanism continues in operation to feed the can-bodies forwardly on the soldering-horn when the clutch device e, before referred to, is operated to stop the body-forming mechanisms. In case a can-body becomes jammed in the edging or formin mechanisms or the machine becomes clogged for any reason it can be stopped by disengaging the clutch e from the wheel e without stopping the conveyer for the soldering mechanisms, which thus carries the canbodies past the soldering devices and prevents the hurning of the bodies.
